please try the attached patch. it will add the SB mixers (all new ones starting "SB xxx" except for tone controls) and initializes the SB-mixer reg bit (as default). the first step is to check whether and which SB mixer has influence to what output/input. there are also CMI8330-native controls, namely the controls without "SB" prefix. whether these controls affect the playback. the SB mixers can be disabled (removed) by commenting out ENABLE_SB_MIXER definition in the source. the next step is to switch playback and capture by commenting out the definition PLAYBACK_ON_SB at the beginning of the code. then the playback will be done through AD1848 and capture will be on SB16. check again which mixer elements work for what. ciao, Takashi
